Binkley-Ober
Quarry, East Petersburg, PA - November 13,2004

On November
13,2004, 10 mineral collectors braved the cold windy conditions to
visit the Binkley-Ober Quarry in East Petersburg.Once
again, this was the first DMS trip into this quarry in a number of years.This is
also an active quarry that mines the limestone, dolostone, shale and sandstone of the
Cambrian age Buffalo Springs Fm. for road aggregate and cinder blocks

The
group included 9 DMS members (Joe Meloney, Ken Casey, Tim Cretien, John Osoinach, Karissa
Hendershot, Carl Muendel, Jeff Chalfant, Tom Pankratz and me) along with Jim Schoonmacker
from the MGS.

The
most notable find of the day was made
by Joe Meloney, whose very nice
specimen of pink dolomite is pictured on the DMS web site.

All
of us came
out of the quarry with numerous specimens containing calcite crystals, pink dolomite crystals, and purple fluorite and had a
good time while collecting them!
